The big-money fundraiser comes as good-government groups continue to push for campaign-finance reform, including the public funding of campaigns. Cuomo has said he support public financing, but he's yet to be able to strike a deal with the Legislature.

The groups wrote to Cuomo's Moreland Commission today urging the group to look into the state's porous campaign-finance system.

In the letter, the six groups said there have been good ideas presented to the commission on how to root out corruption in Albany, but campaign-finance reform needs to be addressed.

"We fully support many of these ideas, but want to ensure that you do not lose sight of the fundamental problem of both legal and illegal corruption in Albany: the 'show me the money' culture that permeates state politics," the groups wrote.
